Files with non-ascii path are not pushed to svn

[IWATA Hidetaka]

This problem is in both bzr2.3.3 and bzr2.4b3

Changes in the non-ascii named folder does not pushed to SVN.

To reproduce::
  SVN repository layout
    trunk
    + テスト (non-ascii folder)

  >bzr branch url/to/svn/repos/trunk trunk
  >cd trunk

  >echo foo>テスト/foo.txt
  >bzr add
  adding "テスト/foo.txt"

  >bzr commit -m "add file to NON-ASCII folder"
  added テスト/foo.txt
  Committed revision 3.

  >bzr push url/to/svn/repos/trunk
  Pushed up to revision 3.

No errors are occurred, and the svn repository has new revision now,
but no files are in the changeset of that revision.

I can't reproduce this with bzr-svn trunk:

I've forgotten to mention about environment.
I use Windows 7, perhaps you tried to reproduce it by Linux?

It seems that dir_editor_send_changes in commit.py is wrong.

`visit_dirs` contains unicode values, but `new_child_path` is already encoded to utf-8.

This patch will fix it, but maybe not best solution.
